23035ca68d [PATCH] gethostbyname(): correct returned address format when DNS is used. The hostent.h_addr_list should point to raw in_addr or in6_addr as defined in the standard. Original implementation used that
for numeric addresses but for DNS lookup returned pointer to whole sockaddr_in or sockaddr_in6.

getaddrinfo() should be preferred in a long term perspective. Return of complete addresses from the lookup would be better in such case but it requires significant changes anyway - multiple addresses support and most probably dynamic memory allocation which is bad for many RT applications. So gethostbyname() is sufficient for most applications now.

5ace3311d9 Repartitioning of DNS client logic in preparation for IPv6 support
- Rename include/nuttx/net/dnsclient.h to dns.h
- Move internal DNS prototypes from dns.h to libc/netdb/lib_dns.h
- Global standard DNS definitions from libc/netdb/dns_soccket.c to dns.h
- Eliminate dns_gethostip().  This is now an internal part of gethostbyname()
- Eliminate interface dns_whois().  Not needed in this new context.
